whoa, 5'11 and XL? 

I'm 5'11 as well, currently riding a trail bike which starts to feel too short (reach 430mm, had to install a longer 65mm stem but it still doesn't feel right). 

I'm eyeing the V3 Bronson, wasn't sure about M or L size, but it seems L will be perfect, and I fall right in the middle of L on their current sizing chart...
